- Abstract
Patients with pemphigus may produce antibodies against molecules other than the classical transmembranal ones. Recently, for example antibodies to 230 kDa antigens have been found in association with antibodies to intercellular substance. To better understand their prevalence, clinical correlates and prognostic significance of bands other than 130 and 160 kDa, we studied 67 pemphigus sera. About one-fourth of patients revealed multiple heterogeneous bands and 13% the 230 kDa band. When challenged with the recombinant protein rBPP55, the carbossiterminal portion of hullous pemphigoid major antigen, all 230 kDa-positive-sera proved negative. Caution is to be recommended in interpreting pemphigus sera with a hand migrating at the 230 kDa level.
